The presence of voltage is indicated by an indication on the lcd display and a diode lighting up.indicator functionsdetection of ac and dc voltage using the contact method: 12 - 250vdetection of ac voltage using the inductive methodwire continuity testcontact methodplace the tip on the live circuit. The display will display the voltage values and the diode lighting up indicates electric current flowing through that element. The indicator will show the highest voltage range for the tested circuit and all lower ranges. For example when measuring voltage from a 230v household socket the display will show [12 36 55 110 220] which means voltage above 220v. The display indicates the correct voltage ranges for the ac waveform when the contact test field is held down. For the dc waveform the correct ranges are displayed when the induction test field is held down.inductive methodthis method allows you to detect ac voltage in an insulated wire. To do this place your finger on the induction test field and bring the tip close to the insulated wire. The presence of a lightning bolt symbol on the lcd indicates the presence of voltage. This method also allows for non-contact detection of a break in a live electrical wire. At the point of break the tester will stop signaling the presence of voltage.checking wire continuitycheck the continuity of the wire by touching the tester tip to one end of the wire then while holding the contact test field grasp the other end of the wire. The led will illuminate to indicate the continuity of the tested wire. It is prohibited to use this method to check the continuity of wires that are live or in an electrical circuit.**
